To all whom# may concern.' Be 1t known that .1, ANTOINE 'JosErH Marins BARTHE'LEMY DITPAUL CANsfcitrzen of the Republic of France, and residentV of Paris, France,'have invent-edul new and useful Fire Escape, which improvements are fully set forth inthe following specification; ln case of a. building` getting' afire, salvage has been effectuated hitherto by means of ladders and ropes permitting the persons endangered to -bev brought down to the ground. But everytime a person or thing; is brought down, the firemen have to climb upA again to the stories, whether theybodily accomplish the salvage or use ropes.

This method involves drawbacks r' itre-l quires far too longA a time, while beingdangerous and laborious both for dangered'and forrescuers.Y Y Y Y l v rEhe Vobject of my invention is to provide a device which;allowsV the aforesaid Vdrawbacks to be done away with, this is to say` persons enlthat will allow'fimmediate@and prompt rescue, with aredu'c'ed number of rescuers while affording* comfort and great safety.

My device 'can be used either` any endangered person or by 'the rescuers and' requires only a rope affixed ataproper spot on the building and'leading to vthe groundf My device is characterized bythe fact that two fixed Vrollersv are combined with vmobile one,1such -rollers being' Yp roperlyvadjuste'dV between two suitable crossties, permitting instant fixing of the device to the rope at anyheig'ht without the ends'of the said rope having' to between the rollers. Y Y i I Suitable means yare preferably provided to enable the device to be secured 'tothe belt' or waist of any endai'igered person orl perlbe lpassed or :threaded Vsons who, 4jumpingou't, lwill, descend at a spedavliich they are enabled to regulate simply by pulling on therope, braking be'- ing ensured vby the free playof the Vmobile runner which is automatically moved to-` wards the fixed runnersgby the horizontal thrust caused by the increasedtension in the rope and from the-fixed runners .by the resistance offered by the elasticV properties of the rope in resisting the clampingeffect produced between thedixed. andA mobile runners.. f: -l

In the case where the endangered parties are inert, or again i-n the case where Lobjects or things 'are to`V berescued, thedownward speed is adjusted by a fireman stand-v Figure l ingv at the lower end-fof therope and .whose functionor dutyis simply to exerta proper' pull upon thef'rope and tounhoolr' the .de-` viceiand its load whenthe-latter reaches the'groundf 1 Y' In order to inalre my invention rmore clearly understood, I haveillustrated, as-an A man@v showing As will be seen,the iescape? performed :is

by the deviceand theplowering `speed may beL regulatedk by 'al mere 'pulling onA vthe lower length orl portion of the' rope'.

ri method of using umr-afofedescribea fescape is as followst.

Whenv the device is to beused" for'tfhe rescue Yofa number ofpersons, who maybe entrapped in a burning building, the fireman or.l any other person'being equippedl with 'a rope and lany number'l of theattachments, itv willonly be necessary to secure one end ot the rope tojany desiredisupporti upon the building, the other end of the rope being thrown down so that it will hang tothe ground. The mobile roller ai. on each of the devices' it"is"desired to usev is thrown" to the position shown in Fig. l, a loop is quickly` made in the rope and inserted between the rollers c, after which the roller d is turned upon its pivot so that the loop of the rope willextend aroundtheouter face ci the mobile roller in the posit-ion shown in Fig; 2. It will'be understood that the rescue devices may be attached to either ot the axles g, will also be attached to thebelts or aroundV the waist ofv the person whom itis desiredY to rescue; lt' is only necessary then,` that the person endangered shall jump out from the window and allow themselves to descend to the ground. The speed of descent can beregulated by theY person using. the escape by merely placing,` tension upon" the lower portion of: the rope se as to cause the mobile roller l to' move inwardly towards the fixed rollers, which obviously will produce a clampingjeft'ect upon the rope between the rollers. It" the person being'resoued is unconscious or otherwise unable to regulat'ethe yspeed'ofA descent by placing tension upon the lower portion' of the'rope, the speed ofthe descent canfbe regulated by the firemanor other person upon the ground bymerely exerting a pull: upon lthe rope to check the` descent as desired.. lhile the downward journeyY of one person is taking place; the iremanat the top-oi the rope will in the meantime' be'enabled to attach Vanother device and send-down another person without"l having-toA give any further attentiener thought tothe device after it is started on its downward journey,

It Vwill be obvious that private homes may be; equipped Vwith a device oi' this characteigand thatall of the people be rescued' without'havinp; to wait tor the'arrivaloit thewfire apparatus and that it also Vmaybe effectively usedtor' salvan'ino; urni- ,Y ture or other. articles; y

stood that the device willbe ot `great value.

i It will also bel underas fa fire escape for. use with houses, workshops or other places where. a numbery of"l people are employed.
